Kelp-incinerator.

To all whom it may concern.

Be it known that we, HOWARD W. J onsoN and HERBERT ArLOWMAN, citizens of the United States, residing at Long Beach and Wilmington, respectively, in the county of Los Angeles and State of California, have invented new and useful Improvements in Kelp-Incinerators, of which the following a specification.

This invention relates to an apparatus for burning kelp to ashes.

It is the principal object of this invention to provide a furnace within which kelp may be reduced to kelp ash in a rapid and thorough manner.

Another object of this invention is to provide means whereby a large quantity of kelp may be subjected to the flames of a burner at a single time and will thereby increase the production over that of most furnaces now in use.

Another object of this invention is to provide a kelp furnace which may be A heavily fed and which is not liable to bevide a series of kelp receiving bars within come choked.

Another object of this invention is to .pro-

a kelp incinerating furnace which will insure that the flame from the furnace burner will act equally upon all of the kelp within the furnace and thereby produce a high grade ash.

Another object is to provide a means of incinerating kelp which will uniformly reduce it to. an ash of commercial value. and in a rapid manner.

It is a further object of this invention to provide an apparatus for incinerating kelp which is simple and effective and may be operated contmuouslywithout necessity of closing down for-repairs or in order to remove the ash.

Other objects will appear hereinafter. The invention is illustrated, by way of example, in the accompanyingdrawings, in which: Figure 1 is a view in vertical transversesection as seen through the preferred form of furnace construction. Fig. 2 is a view in section and plan as seen on the line 2-2 of Fig. 1 and illus trates the staggered arrangement of the furnace kelp receiving bars.

Referring more particularly to the drawprovided with a bottom 11 and Specification of Letters Patent. P t t M 12, 1mg; Application filed December 10, 1916. Serial No. 137,890. I

which is a top 12. The shell and bottom are lined with a heat ings, 10 indicates a furnace shell insulating lining 13, while the top is here shown as formed with a fiue opening 14 and a charging opening 15 through which the kelp may be fed to the furnace. The chargin opening is fitted with a door 16.

eferring particularly to Figs. 1 and 2 of the drawings it will be seen that the furnace here disclosed is provided with a series of horizontally extending kelp receiving bars 17. These bars are of various lengths and are staggered in relation to each other asthey extend radially from the inner Wall of the furnace. Positioned beneath the bars and adapted to supply heat and flame to t the furnace is a suitable oil burner 18. It is evident, however, that other types of burners might be used with success. provided with an oil feed pipe 19 and an air pressure pipe 20. The shell of the furnace is formed with one side opening 21 This burner is through which the ash may be removed.

This opening is fitted with a hinged door 22 by which it may be closed when desired.

In the operation of the invention opening 15 where it will become lodged the kelp is fed into the furnace through charging upon the various radiallydisposed bars and will be distributed through the interior of the furnace. The burner 18 will be in operation and will produce a suflicient degree of heat to reduce the kelp to ash. It is. evident that, due to the staggered and irre lar arrangement of the kelp receiving ars, the lengths of kelp will be festooned upon the bars and will so remain tom" of the furnace as ash.

It will thus be seen that the apparatus for incineratin kelp for the purpose of reducing it to a as here disclosed, involves the use of a simple furnace construction.

until they have become charred and have fallen to the bot-- the preferred COD:

roe

same distance above and co-axially therewlth, and kelp reoeiv cally arran ed cylindrical shell provided.

with a flat ottom and an outlet door immediately above the bottom, a top shell forming a flue and a chargmg opening; the flue being at one side and the chargin opening being large enough to receive ke p from, a pitch-fork; a cover for the charging I openmg, a burner mounted the bottom of the shell ing bars extending horizontally and radifor the ally inwardly from the shell toward the center and in sta gered relation to each other; said bars being of diflerent lengths, each extending only part way across the shell, and arranged from the level of the burner upwardly to the top of the shell; so that kelp may be pitch-forked through the charging opening to the bars and so that the ashes may be removed from the bottom below the bars through the door below the burner.

In testimony whereof we have signed our names to this specification.
